Question

2 chidren are at the ends of ironpipe One of them strikes theend
of the iron pipe with a stone find the ratio of time taken by the
sound waves in air and in iron to reach the other child (speed of
sound in air = 330 m/s , speed of sound in iron =5200 m/s )
PLS, COULD ANY ONE EXPLAIN THIS !!

Hansraj Rai · Accepted Answer

Let the length of the rod be l
Time taken by sound wave to cover distance l in air is,
Time = Distance/ Speed
t = l / 330 (i)
Time taken by sound wave to cover distance l in iron rod,
Time = Distance/ Speed
t' = l / 5200 (ii)
Therefore,
t/t' = 5200 / 330 = 15 76
